In stock trim, I think they where in the low 300's. It was somewhat detuned for the family car it came in, though.

It has an extra rotor, which means overall the engine is capable of about 150% the performance of a 13B given the same percentage of air and fuel per rotor. Kinda like the difference between a well tuned 2.0l piston engine compaired to a well tuned 3.0l piston engine.
